433M Low cost RF module of CC1121 transceiver

N511BS module based TI CC1121 transceiver. Compare with CC1101, CC1121 has better sensitivity, higher output power, 128 bytes FIFO. The module made with CC1121 transceiver is better than CC1101 transceiver module. The CC1121 module is slightly larger than cc1101 module only.

CC1121 transceiver Description

CC1121 transceiver device is a fully integrated single-chip radio transceiver designed for high performance with very low power consumption and low voltage in cost-effective wireless systems. All filters are integrated, thus eliminating the need for expensive external SAW and IF filters. The equipment is mainly used in the ISM (industrial, scientific and medical) and SRD (short-range equipment) bands of 274-320 MHz, 410-480 MHz and 820-960MHz. To program the registers of CC1121, can be change the frequency of 136.7-160, 164-192, 205-240, 273.3-320, 410-480, 820-960Mhz.

CC1121 devices provide extensive hardware support for packet processing, data buffering, burst transmission, clear channel evaluation, link quality indication and radio wake-up. The main operating parameters of the CC1121 device can be controlled through the SPI interface. In a typical system, CC1121 devices will be used with microcontrollers and a few external passive components.
